Math and STEM

Official V4-Pro copy puts math, STEM, and coding next to closed flagships. V3.2-Speciale’s older note even talked about contest medals. I do not rest a review on a medal table I did not sit. I do rest it on a boring test: 9.11 versus 9.8. With Thinking on, V4 treated them as decimals. That is the failure mode I still watch.

For derivations I keep effort high and I re-solve the last line. Thinking is a scratchpad, not a certificate.
